Lipids are biomolecules that are made up of fatty acids.
By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?(1 point)
This is true because photosynthesis produces glucose, which has carbon, hydrogen and oxygen—the building blocks for all biomolecules.
This is not true because plants need to sequester nitrogen from the soil to build amino acids.
This is not true because plants need to perform cellular respiration to break down the glucose into carbon, hydrogen, and oxygen.
This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.

This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.
This is not true because plants need to sequester nitrogen from the soil to build amino acids. While photosynthesis produces glucose, which provides carbon, hydrogen, and oxygen, plants still require nitrogen from the soil to synthesize amino acids and build proteins.
